No. 11/767,867, filed Jun. 25, 2007, which claimspriority under 35 USC 119(e) to U.S. Provisional Patent Application Ser.No. 60/848,080, filed on Sep. 30, 2006, the entireties of which arehereby incorporated by reference.

FIELD OF THE DISCLOSURE

The present disclosure pertains to manipulation of embroidery designsand, more particularly, to methods and apparatus to manipulateembroidery designs via a communication network.

BACKGROUND OF THE DISCLOSURE

A wide area network is traditionally used to describe a set of devices,for example, personal computers, cell phones, or web servers, that areconnected to each other via digital communication links that may spansmall or great distances. The Internet is a good example of a wide areanetwork that predominantly connects home or business computers to largernetwork servers to provide services such as e-mail, web browsing, orinstant messaging. Wide area networks may use a variety of protocols tofacilitate digital communication over sometimes unreliable orperformance varying physical mediums such as telephone wires, televisioncable networks, or fiber optics. Examples of such protocols includeTransmission Control Protocol/Internet Protocol (TCP/IP), Domain NameSystem (DNS), and Hypertext Transfer Protocol (HTTP). These protocolsare also often utilized with specific data formats such as HypertextMarkup Language (HTML) and Extensible Markup Language (XML) to transferdata between two or more points in a reliable and consistent way.

It is also useful to note that the performance of wide area networks,for example how fast data is communicated over links and what latenciesexists during communication, may vary substantially when compared toother types of networks such as Local Area Networks or Storage AreaNetworks. For example, a personal computer using the Internet may send amessage requesting a web page from a distant server where thetransmission of that request may be relatively slow, for example at adata rate of only a few kilobits per second, and may have a largelatency associated with it in that several seconds may pass whilewaiting for a response to be initiated. When a response is sent, thetransmission of that response may occur at a different data rate, forexample several megabits per second, allowing the personal computer toreceive much more data than what was originally sent in a much shorterperiod of time. The times and various latencies required to transmitdata over a network are important factors to be considered. Morespecifically, in order to improve systems and methods of communication,it is a common goal to reduce the amount of information that must betransmitted over a network. Furthermore, such improvements will oftenfavor transmitting requests that are significantly smaller than theresponses they invoke, for example, measured in the number of bytestransferred.

The above concerns and needs are evident in practically all modernmanufacturing processes, including embroidery. Embroidery is the resultof creating designs or artwork by sewing stitches of thread at specificlocations on a substrate, for example a garment, such that the stitcheswhen viewed as a whole create the appearance of the design or artwork.With the advent of computer controlled embroidery machines many decadesago, the process of creating embroidery was substantially improved byallowing fast and highly precise placement of stitches such that largerand more sophisticated embroidery designs could be much more easilyproduced. These computerized embroidery machines accept input data thateffectively specifies a sequence of coordinate locations, for example xy positions, where each location is typically paired with a specificmachine command, for example, sew stitch, trim thread, change needle, orthe like. This is a type of embroidery data called low level input data,often referred to as stitch data. Low level stitch data can be quitelengthy and may specify designs containing sequences of many thousandsof stitches. Other types of embroidery data include one or more ofhigher level embroidery data, vector data, composite data, low levelstitch data, wireframe data, image data, rendered image data, or thelike.

Embroidery data is also often created when people use embroiderycomputer aided design (CAD) systems or other software that assists ingenerating the lower level stitch data needed by computerized embroiderymachines. For example, using such systems, a user may simply specify arectangular area as well as a few parameters such as angle, stitchlength, and direction to have the area filled with parallel rows of aparticular type of stitching. In many cases, this is highly preferredover having to manually specify the exact location of every stitchwithin the rectangle. This rectangle as well as other various primitivetypes, for example arced or straight columns, Bezier paths, or the like,combined with user specified stitching parameters constitute anotherform of embroidery data referred to as wireframe data. It is often moreconvenient for people to manipulate wireframe data, for example toperform scaling or other editing operations, rather than adding,deleting, or moving individual stitches. Furthermore, this wireframedata is often grouped into even higher levels of abstraction such asindividual letters within an alphabet to allow easier creation ofwireframe data representing lettered designs in a particular font style,for example, monograms and names.

Many prior art methods exist for creating wireframe data both manuallyand automatically as well as methods that convert such wireframe datainto other forms of embroidery data, such as lower level stitch data.Furthermore, many prior art methods also exist for previewing wireframeand lower level stitch data on a display device. For example, in somecases, stitches are represented as colored line segments or in othercases they may be rendered to look more similar to the appearance ofstitches on an actual fabric substrate. Regardless of the actualrendering methods or CAD systems used, prior art here typically entailsrunning computer software on computers that are within the samegeographic location as users. Prior art does not include considerationsor optimizations to allow a combination of such methods and systems tooperate well over a wide area network.

DETAILED DESCRIPTION OF THE DISCLOSURE

In the description that follows, with reference to FIG. 1, a method andsystem to create and manipulate embroidery designs within the context ofa wide area network transfer, various types of embroidery data 10 a-eare described. It is also important to note the differences between theembroidery data 10 a-e shown. The first data type, text object data 10a, shows very high level data, for example a high level of abstraction,while letter data 10 b, embroidery line data 10 c, stitch primitive data10 d, and low level stitch data 10 e show subsequently lower levelembroidery type data with low level stitch data 10 e depicting thelowest level of abstraction. In FIG. 2, some such data is passed betweena client 20, for example a home computer, and a server 21, for example acomputer providing HTTP data. FIG. 3 depicts the typical steps oractivities involved in the process as a whole. These steps include:client request 30 a, request encoding 30 b, server receipt 30 c,document creation 30 d, response creation 30 e, server response 30 f,client receipt 30 g, and client editing 30 h at which point a new clientrequest 30 a is often eventually initiated based on the results ofprevious methods. The transfer process is often initiated by the client20 when such activities are desired by a client user. As used herein,“embroidery data” means any of text object data, letter data, line data,stitch primitive data, low level stitch data, vector data, compositeobject data, rendered image data, or geometric affine transformationdata. “High-level embroidery data” is defined as any type of data types10 a-d, composite object data 50 constructed from stitch primitive data10 d or geometric affine transformation data.

Referring to FIG. 3, the client request 30 a method allows a client userto request that embroidery data 10 a-e be created or modified. Aninitial client request 30 a ultimately may cause the server 21 to send aresponse that includes actual software to be executed on the client 20.Examples of such software include Adobe Flash® files, JavaScript® orother code that may be executed on the client 20. This software may thenbe utilized on the client 20 to further facilitate client requests 30 aas well as the receipt of server responses 30 f to such requests.Referring to FIG. 4, an example of the appearance of such client 20software within a client 20 web browser is depicted. FIG. 4 shows anembroidery design, for example the word “Test”, within an example userinterface 40 window created using an Adobe Flex a Flash/XML basedplatform, for example, software that executes on the client 20. Usingthis software, a client user may, for example, specify text as well as aparticular font or typeface and size before clicking on an insert button41 to create an embroidery text object 42 and view it within a providedpreview window 43.

Client software allows client requests 30 a to occur even withoutexplicit interaction from the user. For example, a client request 30 acan be generated indicating that the server 21 should provide thumbnailimages for all fonts or typefaces available to create embroideredlettering. The user interface 40 may then receive those images anddisplay them at appropriate numbered locations, for example within ascrollable list view, where the number of the location may be used toidentify the font. Thus, the client software may generate many requestssimply to populate various elements of its user interface 40, forexample, thumbnail images of garment backgrounds, thread color lists,text effect options, or line or fill area drawing options. One benefithere is that the client user is able to use client software to generatemore concise client requests 30 a as well as to receive more conciseserver responses 30 f.

Referring back to FIG. 3, the request encoding 30 b step is typicallyperformed within client software. In the preferred embodiment, a clientuser may type text within an edit box, select a font, and select a size.Then, when an insert button 41 is clicked, a request is encoded. In thiscase, the font choice may be represented as an integer within some rangeof values, for example 1-4000, the request encoding step 30 b may thenrepresent that integer as a number using a base higher than base-10, forexample, base-64. Thus, using numeric digits as well as upper and lowercase letters and symbols a number may be encoded using fewer characterswith reference to FIG. 5. This is sometimes useful when generatingrequests that use HTTP since this protocol is used to send charactersand if there are fewer characters in the request, that request may besent more quickly. This type of encoding may also be employed whenrepresenting floating point numbers. More specifically, a 32-bit or64-bit floating point value, as encoded using the IEEE 754 floatingpoint standard, can be converted to a 30-bit floating point value, forexample, modeled after the 754 standard using two fewer bits for theexponent. That 30-bit value may then be converted into a 30-bit integerand translated to a five character base-64 number. Considering thisexample request, a user may specify the word “Hello” of five characters,assuming 64 character choices per character. The user may then select afont from an example choice of 4000 fonts, and a text size assuming a30-bit floating point value, the request could be encoded by simplyappending twelve characters to an HTTP uniform resource locator (URL).This is assuming five characters for text, two characters for fontchoice, and five characters for font size. Additionally, it is alsopossible for client software to apply one of many various compressionalgorithms to further reduce the number of characters, or data, requiredto be sent within the encoded request. Sending an encoded request thatcontains very high level types of embroidery data (refer to the types ofdata 10 a-e defined above) often significantly reduces the size of therequest making more complex requests feasible from a practical viewpointand allowing them to be transferred relatively quickly.

The server receipt step 30 c executes on the server 21 and receives theencoded request data from the client 20. This data must first bedecoded, reverse mirroring the operations that occurred during requestencoding on the client 20. For example, a number of things may becontained within a request to be decoded including items such as thenumber of text objects 42 to create, text object data 10 a, embroideryline data 10 c, thread information, garment information, and variousother parameters that may control the generation and appearance of anembroidery design.

The document creation step 30 d executes on the server 21 and uses thedecoded high level types of embroidery data (refer to the types of data10 a-e defined above) to create a document on the server 21 similar tothat which is compatible with typical embroidery CAD or design creationsoftware. When a document is created additional lower level types ofembroidery data (refer to the types of data 10 a-e defined above) may becreated including low level stitch data 10 e. With reference to FIG. 6,other types of data created include composite representations 50 ofstitch primitive data 10 d. Composite representations 50 may be createdusing the same metafile compositing techniques disclosed in a previousapplication. For example, these representations allow edge contours tobe generated for consecutive sets of column primitives 51 a, onlyseparated by straight primitives 51 b or stitching, that overlap forminga single contiguous region. This document may then be used by subsequentprocessing methods to facilitate their operation.

With reference to FIG. 7 a-c, the step of response creation 30 e usesthe document to create rendered images 60 of the low level stitch data10 e, for example on a garment background if specified, as well as highlevel embroidery data corresponding to those rendered images 60, forexample, wireframes, text objects 42, composite representations 50, orline data 10 c. In this preferred embodiment, two separate image filesare created, one file rendering just the substrate 61, for example apicture of the garment that will be embroidered as shown in FIG. 7 a,and other image file containing a realistic rendering of embroiderystitch data 10 e associated with the document and depicted on a smallersubsection 61 a of the overall substate 61 as shown in FIG. 7 b. Boththe images are placed on a preview window 43 area of a user interface 40specified by the client 20 such that when the stitch rendered image 60is placed on top of the substrate 61, a preview image 62 as shown inFIG. 7 c is formed similar to one that would result if a picture wastaken of the embroiderable product after it was actually embroidered ata physical manufacturing facility. The two images created may beproduced at different resolutions, for example dots per inch (DPI), butit may then be useful to modify their size through a process commonlyreferred to as resampling, such that they are ultimately provided at thesame resolution. Rendering may also occur in three-dimensional space ifthe substrate 61, or embroiderable product, is not flat in itsappearance. This can be achieved through a process commonly referred toas texture-mapping, where the stitch data rendered image 60 isconsidered as a texture. When creating the stitch data rendered image 60it is also useful to note mappings between locations in that image andlocations within the substrate 61. More specifically, for eachcoordinate position in stitch data rendered image 60, it can bedetermined where, for example at what coordinate position, within thesubstrate 61 image that position lies. This is useful so that the colorsof rendered thread used to simulate the appearance of stitches can bepartially combined with colors of the product image to provide asmoother and more realistic rendering, effectively achieving a resultcommonly referred to as anti-aliasing or super-sampling. The responsecreation 30 e step also places information within the response toinstruct the client 20 where and how these images are stored.

As mentioned previously, in addition to the creation of images, actualembroidery data 10 a-e is produced in the response creation step 30 e aswell. This data is created to facilitate display and editing capabilityat the client 20 and is formulated to correspond directly with theimages provided, for example, in scale and offset. This data mayindicate the presence of a text object 42 containing multiple compositerepresentations 50 at a particular location where the one or more edgecontours of each composite representation 50 are approximated bypolygons. The coordinate position of each vertex on each polygon mayalso be generated and supplied. Coordinate positions for end points orarc points within embroidery line data 10 c are another example ofembroidery data 10 a-e supplied. In general, much of the embroidery data10 a-e supplied here may broadly be referred to as vector data since itlargely comprises vertices as well as indicating lines that connectthose vertices. This is in contrast to image data which may only includepixel data.

The server response step 30 f takes the response created previously andformats and transmits it to the client 20. In the preferred embodimentpresented here, this data is transmitted in the form of XML and imagefiles over HTTP. XML data may also be encoded or compressed using aprocess similar to that used when generating a client request 30 a. TheXML file contains the absolute URL of the image files created andembroidery data 10 a-e related to those image files. FIG. 8 shows anexample excerpt of non-encoded XML data.

The client receipt step 30 g receives the previously transmittedresponse at the client 20 and decodes and or decompresses it ifnecessary. This process also translates and stores the data receivedwithin native data structures stored locally at the client 20, forexample, within a client 20 random access memory (RAM). Storing highlevel embroidery data locally allows the client 20 software to displayand modify that data locally within its user interface 40 withoutneeding to send additional requests to the server 21 which could have asubstantial effect on the responsiveness or latency of the userinterface 40.

The client editing step 30 h typically operates as part of client 20software that executes at the client 20 and allows various means toview, manipulate or edit the embroidery design presented to the user.This includes displaying the provided rendered images 60 and 61 atappropriate locations, for example centered and on top of each otherwithin a preview window 43, and overlaying high level embroidery data,or vector data, on top of one or more of the images when needed. Oneinstance where such vector data is useful is to keep track of thepolygonal areas of composite representations 50 such that the method maydetect when a mouse cursor clicks or moves within the bounds of such anarea. Hence, this allows the client 20 user to click on the image toeffectively “select” a text object 42, a letter within a text object 42,a composite representation 50, for example within a single letter, orany other high level embroidery data that is represented using vectordata.

In addition to selecting items within a user interface 40, the client 20user may edit such items by using other facilities within the clientediting step 30 h as in FIG. 9. For example, by holding a mouse buttondown when the mouse cursor is over an item, and then dragging the mouse,the item may be moved or translated to a new position on the substrate61. The client editing step 30 h may also present various control pointsor regions within the user interface 40 that allow many other types ofediting. Small square areas, for example user interface (UI) regions 70,may be displayed around the bounding rectangle 71 of an item such thatwhen these points are clicked and dragged by a client 20 user, therelated item may be scaled or rotated. Other UI regions 70 that allowcharacter kerning within text objects 42 or applying various effectssuch as arcing may also be supported. A significant benefit to thismethod is that while the mouse is being clicked or dragged in thesevarious ways, the actual effects of the edits may be visible inreal-time by applying such edits directly to the vector data storedlocally in RAM and then displaying the vector data within the previewwindow 43, for example, overlapped on top of the rendered substrate 61image. The visual feedback that this provides to the client 20 allowseasier and more precise edits since the precise size, position, andorientation of items may be viewed while performing the edit.

The client editing step 30 h is also responsible for initiating newclient requests 30 a to send updated high level embroidery data to theserver 21 which ultimately results in new rendered stitch data images 60and updated high level embroidery data being sent back to the client 20.These new client requests 30 a often contain information describingtransformation matrices and other data that allows the edits thatoccurred on the client 20 to be applied within documents being createdon the server 21. Because many requests may be generating while a client20 makes edits, these requests may be numbered sequentially where thenumber is sent along with the request to the server 21. This will allowresponses to be labeled with those numbers as well making it possiblefor the client receipt 30 g process to ignore responses that may nolonger be relevant, for example, due to the initiation of newerrequests.

It is also useful to note that the method and processes disclosed withinthis application may be further extended by their combination withmethods disclosed within previous patents and patent applicationpublications of the inventor(s). More specifically, a client request 30a may contain image or metafile data, for example in addition to orinstead of other high level embroidery data, for the server 21 toautomatically convert into embroidery data 10 a-e using previouslydisclosed steps. This image or metafile data may be supplied by theclient 20, for example via image files that were resultant from scanningpictures using a computer scanner or for printing documents using aprinter driver (e.g. see application entitled Printer Driver Systems andMethods for Automatic Generation of Embroidery Designs).

From the foregoing, it can be seen that the teachings of the disclosureset forth a method and system for creating and manipulating embroiderydesigns over a wide area network. The method includes steps to transmitvarious embroidery design data over a wide area network between a clientand a server.
